A simple game, could be quite interesting.

A game that could very easily be played in a bar, making the lives of others more interesting.

Played with liquor not beer.

Supplies: people, a variety of liquor, and a deck of cards.
  Shuffle the cards.

Start dealing one card at a time, face up, to each player.
The first person to be dealt a king picks a liquor, the second dealt a king picks the mixer, the third makes the drink (or buys it), and the last dealt a king drinks it.

This can turn out to be quite a laugh; it relies purely on chance, and if you pick a really disgusting liquor or liquor / mixer combination, it could happen that you'll be the one required to drink the concoction.
